Abstract: Software development tools and techniques for configuring parallel processing systems to execute software modules implementing processes for solving complex problems, including over-the-counter trading processes and foreign exchange trading processes, to execute quickly and efficiently. The parallel processing system may include low-cost, consumer-grade multicore processing units. A process for solving a complex problem may be divided into software modules, including by evaluating the process to determine discrete processing steps that produce an intermediate result on which later steps of the process depend. The software modules created for a process may form a template processing chain describing multiple processing chains of the process that are to be executed.

Abstract: A multi-threaded processor is provided that internally reorders output threads thereby avoiding the need for an external output reorder buffer. The multi-threaded processor writes its thread results back to an internal memory buffer to guarantee that thread results are outputted in the same order in which the threads are received. A thread scheduler within the multi-threaded processor manages thread ordering control to avoid the need for an external reorder buffer. A compiler for the multi-threaded processor converts instructions that would normally send processed results directly to an external reorder buffer so that the processed thread results are instead sent to the internal memory buffer of the multi-threaded processor.

Abstract: An on-demand disposable virtual work system that includes: a virtual machine monitor to host virtual machines, a virtual machine pool manager, a host operating system, a host program permissions list, and a request handler module. The virtual machine pool manager manages virtual machine resources. The host operating system interfaces with a user and virtual machines created with an image of a reference operating system. The host program permissions list may be a black list and/or a white list used to indicate allowable programs. The request handler module allows execution of the program if the program is allowable. If the program is not allowable, the host request handler module: denies program execution and urges a virtual machine specified by the virtual machine pool manager to execute the program. The virtual machine is terminated when the program closes.

Abstract: At least one presently preferred embodiment of the invention broadly contemplates correlating asynchronous transaction parts based on a unique transaction value (e.g. a unique business ID) that all the transaction parts will have access to. This avoids the need for enriching/changing the message body or message header with ARM “correlator” information.

In a method of controlling a computer system including a computer, the computer executes a virtualization program for causing logically divided resources of the computer to operate as first and second virtual computers, the first virtual computer executes a first OS, and the second virtual computer executes a second OS. In the method, information regarding the resources allocated to the first virtual computer and the second virtual computer by the virtualization program is obtained from the virtualization program, information indicating performance of the first virtual computer is obtained from the first OS, information indicating performance of the second virtual computer is obtained from the second OS, the obtained information and information indicating a time of obtainment of the information are stored in a storage system, and stored information is output.

Abstract: One embodiment of the present invention provides a system that facilitates using a web-based client-server application offline. During operation, the system receives a function call at an object within a browser that is executing on a client, wherein the function call is generated by the web-based client-server application and is directed to a communication layer on the client. Next, the system determines an intended resource for the function call. The system also determines if the function call should be redirected to an alternate resource. If so, the system redirects the function call to the alternate resource. If not, the system forwards the function call to the intended resource. Note that in some embodiments of the present invention, the entire system operates within the context of the browser.

Abstract: A method, system, and computer usable program product for selective memory donation in a virtual real memory environment are provided in the illustrative embodiments. A virtual machine receives a request for memory donation. A component of the virtual machine determines whether a portion of a memory space being used for file caching exceeds a threshold. The determining forms a threshold determination, and the portion of the memory space being used for file caching forms a file cache. If the threshold determination is false, the component ignores the request. If the threshold determination is true, a component of the virtual machine releases a part of the file cache that exceeds the threshold. The part of the file cache forms a released file cache. In response to the request, the virtual machine makes the released file cache available to a requester of the request.

By adopting such data configuration of the operational system and the test system, it becomes possible to switch easily and smoothly between the operational system and the test system.

Abstract: A resource management infrastructure (200) is proposed, wherein every resource may be represented by multiple (specialized) objects (B1, C1, D1; C2), which instantiate corresponding (specialized) classes (315) modeling different aspects of the resources. In the proposed solution, an edge class (310) is associated with the specialized classes; each resource is associated with a corresponding edge object (A1; A2) instantiating the edge class (which object is identified by a corresponding edge name). More specifically, the classes are organized into a specialization tree (300); the edge classes directly depend on abstract classes, while the specialized classes in turn depend on the edge classes. Each specialized object is then associated with the edge name of the corresponding edge object. In this way, the specialized objects associated with each edge name represent the same corresponding resource. An optimized structure of a relational database (225, 230) implementing the proposed solution is also proposed.

Abstract: A distributed processing system is described that employs “application-based” specialization. In particular, the distributed processing system is constructed as a collection of computing nodes in which each computing node performs a particular processing role within the operation of the overall distributed processing system. Each of the computing nodes includes an operating system, such as the Linux operating system, and includes a plug-in software module to provide a distributed memory operating system that employs the role-based computing techniques. An administration node maintains a database that defines a plurality of application roles. Each role is associated with a software application, and specifies a set of software components necessary for execution of the software application. The administration node deploys the software components to the application nodes in accordance with the application roles associates with each of the application nodes.
